The invention relates to the art of reproducing diagrams, designs andthe like and is particularly concerned with a novel method of, and meansfor reproduction of designs, diagrams and in general any representationof ornamental or educational nature.

In the graphic arts the reproduction of designs or diagrams was hithertocarried out by producing a drawing of such design and thereafter asingle die was produced which formed a replica of the desired design. Inthis method it is necessary to produce an individual die for each andevery design entaillng a high cost and considerable time for producingsuch dies.

The present invention deals With the reproduction of designs and thelike obviating the necessity of producing drawings to serve as patternsand obviating the necessity of making up unit dies especially ofcomplicated and large diagrams.

It is one of the principal objects of the invention to provide aplurality of die sections or elements which can be assembled to form asingle die dening the desired design or diagram and which segments canbe re-arranged in many Ways to produce varieties of designs.

It is a further object of the invention to secure the die segments inassembled relation so as to obtain the same reproduction as if a unitdie had been used.

Another object constitutes the provision of die segments which whenassembled and brought to bear on the printing or engraving materialunder pressure leave an imprint of a continuous and uninterrupted naturethe same as if a unitary die had been used.

It is also an object to provide certain features of lconstruction andassembly tending to enhance the utility and eliiciency of the invention.

With these and other objects in View which Will become apparent from aperusal of the invention, the latter comprises certain steps in a novelmethod and means for carrying out such method as described in thefollowing specifications, particularly pointed out in the claims forminga part thereof, and illustrated in the drawings, in which:

Fig. 13 is a fragmentary perspective view to illustrate a step incarrying out my process.

Fig. 14 is a perspective view of a special paper employed in the method,and

Fig. 15 is an enlarged section on the line I5-I5 of Fig. 13.

The invention is illustrated in connection with the reproduction ofdiagrams which is of course only indicative of the principle involvedand may be applied to thereproduction of any representation where speedand inexpensiveness is of importance. The principle referred to involvesthe provision of die-elements or sections of various shapes or formswhich may be assembled in any desired manner to assume a desired designand such assembled elements may be used as a unit for obtainingimpressions to provide replica of such desired design.

The Word design is used to indicate any representation either of anornamental, technical or educational nature.

Referring to the various views in the drawing. I0 designates adie-element which comprises a base II of rectangular cross section Whichis integral with a synclined top or head I2 of less width at the basethan the base II so as to de- Iine shoulders I3 and I4. The top face ofthe head I2 is grooved with angular side Walls to dene cutting edges I5and I6.

Attention is called to the fact that in each element the head and thecutting edge are of the same length as the base so that when two dieelements are placed endwise in abutting relation as shown in Fig. 10 atI'I, then the cutting edges are in contact, so that an impression madewith these cutting edges is continuous and no break appears eventhoughthe die is not unitary but made up of elements.

Where elements are placed at right angles-to each other it is alsonecessary to have the cutting edge in contacting relation. To this endthe dieelement I0 is cut away as at I8 and I9- so that the inner wall ofthe cut out portion or recess (Fig. 3) is in vertical registryrespectively with the cutting edges I5 and I6. The die element 2| havingcutting-edges 22 when arranged to lit with one end in the recess ofelement l0 provides for a contacting relation of its cutting edges 22with the edge I6 of element IU. Thus again an impression made .withtheseelements will show no break between the lilines Vproduced by'edges 2v2and 16 Yand thus gives rise to the impression that a unitary die wasused.

The angular element 23 has cutting edges "24 which extend the entirelengthof theelement.

The circular die element 25 is provided Jwith circular cutting edges 26,which are ush with the sides of the element.

The die-element 21 representing letter A shown in Fig. 9 has likewisecutting A'edges 28 ico-rterminous with the base of the element.

No attempt has been made to show all of the 4varieties of elements to beused and only a few *instanceshave been illustrated.

In.Fig. 10 anumber of elements are assembled to ,produce a diagram suchas used to -denote `a radio circuit.

As indicated in Fig. 12 a lplatform 30 is placed on lthe `lower partof1apress l311 Vand a sheet of lchart paper 3l superposedby a layer 32`of 'translucent waxis arranged on said platform.

On such layer 'of wax the elements are ar- .ranged to form thediagramshown in Fig. 1'0rand are "held in assembled relation by the wax the.squares of the chart paper aiding in arranging 'the elementsin properposition.

On-the assembled 'elementsis placed azsheet vof paper '33 `which on the.upper side is covered with a thermoplastic pressure-sensitive kadhesives35.

The other side of the paper maybe covered ywith la y'layer -36 zinc'sulphide 'or vrstrontium sulphide ywhich has luminescent properties.Over thepaper is 'arrangeda cardboard A3l. V'When the lowerpartf'34 ofthe press yis brought up'then the cutting edges of the die element willout out from vthe paper 33 strips forming a replica of the diagram shownin Fig. 10. The surplus paper -not used in lproducing the ydiagram isthen re- `moved.

Thereupon the strips 'as shown in Fig. 13 are 'subjected to 'theinfluence of `an iron I38 whereby the adhesive is heated and cementsvthe rstrips to the 'cardboard 31. y

'The paper 33 may be vof 'any desired Vcolor Yor design or many colorsand where 'portions ofthe diagram uare `to 'have diierent colors, 'thenadditional `sheets or 'strips of paper 39 'may Vbe used in some portionsofthe diagram or design, as shown in Fig. 15. Theemployment Aofdifferent colors vior portions of the design 4meets a long felt needsince it enables the reproduction Yof Vcolor codes.

It is, of course, understood 'that the 4cutting edges of the-dieelements are vin lthe `same'horizontal place so thateven cutting isensured.

The invention has been s'hownto illustrate the principle underlyingthesame.

Numerous changes and modifications may be made wit-houtdeparting fromthe spirit of the zinvention. I, therefore, do not limit vmyself to thesequence of steps enumerated 'in themethod,

nor to the particular construction of elementsv shown, but 'claim myinvention as broadly as the :state ofthe zart ipermits,

I claim:
